ATTORNEYS DEFORMABLE TUBE WITH NOZZLE FOR EXTRUDING PASTELIKE PRODUCTS IN FLA'ITENED FORM This invention relates to a deformable tube for pastelike materials provided with a nozzle which allows the dispensing of the product contained therein in the form of a strip or thin ribbon.

Certain pastelike products, such as, for instance, those used for cosmetics or curative purposes, should be dispensed in the a form of a thin ribbon to be rapidly and suitably spread over the desired surface. The present invention meets this requirement and allows the product to be dispensed and spread by the user with the same hand which holds and squeezes the deformable tube, so that said product is dispensed with the necessary evenness and uniformity. I

The tube in accordance with the invention is characterized in that it includes a nozzle comprising a final, flattened length or dispensing portion provided with a laminating slit or discharge orifice through which the product is supplied in the form of a thin ribbon.

According to the invention, the nozzle is able to retain at its slitted end, by elastic constraint, a cap which seals said dispenser slit and prevents the foreign matters to enter.

In an advantageous embodiment of the invention, the nozzle is made of a molded, plastic material and is removably fitted to the usual nip of the tube, thus extending the advantages of this invention to the usual deformable tubes.

The invention will now be described in the following specification, with reference to the attached drawing, illustrating a preferred embodiment of the deformable tube provided with the nozzle of the invention. ln'the drawing;

FIG. 1 is an elevation view of the tube;

FIG. 2 is a partial front elevation view of the tube, with the plastic nozzle partially sectioned;

FIG. 3 is a plan view of FIG. 2, with the cap removed;

FIG. 4 is a cross section of the nozzle; and

FIG. 5 is a partial enlarged view of the nozzle of FIG. 4.

Referring now to the drawing, A indicates the defonnable tube which retains, as will be explained thereafter a nozzle B the mouthpiece B, of which is provided with a cover C.

The lower end of nozzle B is provided with a female threaded fitting B screwed to the usual nip of the deformable tube A, thus establishing a connection between the inside of said tube and the nozzle. In the illustrated case fitting B is surrounded by a crown B which can be fitted to the top end A, of the deformable tube.

Adjacent to the female threaded fitting B is a tubular length B,, which proceeds towards the other end of the nozzle with a gradually modified cross section to terminate at the mouthpiece B, with a slit B Actually, the cross section of said slit or discharge orifice is slightly smaller than that of the fitting 8,, to maintain the pastelike material under a constant pressure, thus guaranteeing the continuity of the same in dispensing.

As shown more in detail in FIG. 5, the inner wall of slit B adjacent to the dispenser opening, shows a groove designed to house, under elastic constraint a shaped projection C, integral with cap C at its lower end. Said projection extends over a length substantially equal to the width of the slit of the dispenser nozzle B, being retained adherent to the rim of said nozzle by the elasticity of the latter.

Consequently, the nozzle B whether it is integral with the deformable tube A or removably fitted to the same, allows the dispensing of the pastelike product, in form of a thin ribbon, through the nozzle slit 8,, whereby the distribution of the pastelike material can be easily performed, also because the end of nozzle B, showing a spatulalilte shape, allows the spreading of the dispensed material. Cap C can be applied and removed easily, due to the shaped portion C, of projection C,, as well as the rounded edges of nozzle slit, 8,.

The above illustrated nozzle is particularly designed for construction in plastic material.

I claim:

1. A nozzle for dispensing a pastelike product and adapted to be secured to the opened end of a product container, comrisin p an longated, flat and hollow dispensing portion having an opening therethrough, said dispensing portion having a width greater than its thickness and having a longitudinal length at least equal to its width;

said dispensing portion having an elongated and narrow discharge orifice at one end thereof communicating with said opening, said opening adjacent the other end of said dispensing portion being substantially circular with said opening as it extends from said other end to said one end being of a gradually modified cross section with the opening smoothly and gradually flattening and widening as it extends from said other end towardsaid discharge orifice;

said discharge orifice having an area less than the area of the circular portion of said opening adjacent said other end of said dispensing portion, and said discharge orifice having a width greater than the diameter of the circular portion of said opening;

a short, radially enlarged connector portion integrally connected to said dispensing portion adjacent said other end thereof, said connector portion being adapted to engage the opened end of said container, said connector portion having a substantially circular passage therethrough in communication with the circular portion of said opening; and

a removable cap mountable on said one end of said dispensing portion of for sealingly closing said discharge orifice, said cap including a body portion adapted to be disposed directly adjacent said one end of said dispensing portion and a tonguelike projection extending outwardly from said body portion, said tonguelike projection having an enlargement having a width greater than the width of said discharge orifice, and at least the discharge end of said dispensing ,portion being elastically deformable for permitting said enlargement to pass through said discharge orifice for effecting a sealed closing of said opening.

2. A nozzle according to claim 1, wherein said body portion of said cap has a cross-sectional configuration approximately corresponding to the external configuration of said one end of said dispensing portion.

3. A nozzle according to claim 1, wherein said circular passage is threaded for permitting said nozzle to be secured to a container containing a pastelike product. 

1. A nozzle for dispensing a pastelike product and adapted to be secured to the opened end of a product container, comprising: an elongated, flat and hollow dispensing portion having an opening therethrough, said dispensing portion having a width greater than its thickness and having a longitudinal length at least equal to its width; said dispensing portion having an elongated and narrow discharge orifice at one end thereof communicating with said opening, said opening adjacent the other end of said dispensing portion being substantially circular with said opening as it extends from said other end to said one end being of a gradually modified cross section with the opening smoothly and gradually flattening and widening as it extends from said other end toward said discharge orifice; said discharge orifice having an area less than the area of the circular portion of said opening adjacent said other end of said dispensing portion, and said discharge orifice having a width greater than the diameter of the circular portion of said opening; a short, radially enlarged connector portion integrally connected to said dispensing portion adjacent said other end thereof, said connector portion being adapted to engage the opened end of said container, said connector portion having a substantially circular passage therethrough in communication with the circular portion of said opening; and a removable cap mountable on said one end of said dispensing portion of for sealingly closing said discharge orifice, said cap including a body portion adapted to be disposed directly adjacent said one end of said dispensing portion and a tonguelike projection extending outwardly from said body portion, said tonguelike projection having an enlargement having a width greater than the width of said discharge orifice, and at least the discharge end of said dispensing portion being elastically deformable for permitting said enlargement to pass through said discharge orifice for effecting a sealed closing of said opening.
